The basic type is calculation for framed towers

Colleagues: The foundation type for the middle tower in SW6 is framed; does this type of tower rely on its own base for support, or is it merely installed on a frame?
In SW6 calculations, a skirt base with a \"frame\" means that the tower equipment is supported on a frame, which is considered as part of the structurally uniform vertical structure, and is treated as one segment in the segmented calculations. The method for determining the cross-sectional moment of inertia of the support frame is as follows: (1) For a frame with columns arranged in a circular pattern, it can be transformed into a cylinder with a uniform cross-section. (2) For general forms of lattice frames and frameworks, they can be converted into equally stiff bars with equal cross-sections. At this time, the user also needs the frame structure parameter; “no frame” means that the tower equipment is installed directly on the foundation.
